In a nuclear reactor, a core of nuclear material may be confined to a relatively small volume internal to the reactor so that a reaction may occur. A controlled nuclear reaction may persist for an extended period of time, which may include several years, before refueling of the reactor core is required. Accordingly, when used as a source of heat for converting water into steam, a properly designed nuclear reactor may provide a carbon-free, stable, and highly reliable source of energy.
During operation of a nuclear reactor, one or more sensors may be used to measure a neutron flux associated with a neutron source and/or with neutrons generated through fission events in the reactor core. Similarly, it may be useful to monitor the temperature, pressure, coolant level, power level, and/or coolant flow rate within the reactor module to ensure that all aspects of the reactor's internal operation are maintained within acceptable limits. For example, in the event that the flow of coolant is too low, components within the reactor may undergo excessive heating, which may result in the failure of one or more reactor components. In the event that the flow of coolant is too high, the reactor core may experience an undue level of cooling, which may result in undesirable fluctuations of reactor output power levels.
Temperatures and potentially corrosive characteristics of coolant located near the reactor core and/or otherwise located within the reactor module may cause sensors, gauges, and/or other types of measurement devices to fail over a period of time. Additionally, shutting down the reactor to replace and/or repair the failed measurement devices may result in significant operational costs and ultimately a less efficient and less reliable source of energy.
Periodically, a reactor module may need to be refueled, serviced, and/or inspected. Certain types of reactor modules may be removed from the reactor bay and replaced with a new reactor module. In addition to the number of sensors that may be used to monitor various characteristics of the reactor module, additional components, fittings, attachments, piping, wiring, supports, etc. that may be attached, connected to, or otherwise placed in communication with the rector module may impede the ability to gain access to and/or to service the reactor module. Similarly, it may take a significant amount of time to connect and disconnect the various components from the reactor module, such as during installation of the reactor module and removal of the reactor module, respectively. Furthermore, any penetrations into a reactor vessel and/or containment vessel that are made to accommodate the various components may provide potential leakage points and/or areas of structural weakness in the reactor module.
This application addresses these and other problems.
